EF1 tornado in Macon County, Illinois

The tornado began in Logan County, about 1.5 miles south-southeast of Latham. It progressed east into Macon County, entering the county at the intersection of 2400th Avenue and Heman Street, about 1.75 miles south-southwest of Heman. The tornado uprooted softwood and hardwood trees along 2400th Avenue, which is the county line between Logan and Macon counties. As the tornado progressed east along Heman Street it produced extensive damage to several outbuildings, including knocking down several walls and throwing debris for a mile downstream. The tornado snapped some trees and damaged an outbuilding on 500E Road before dissipating a few hundred yards east of there.

A slow moving frontal system aided the development of supercell thunderstorms by mid-afternoon, which eventually grew upscale into a line segment as they progressed across central and southeastern Illinois during the evening. A total of four tornadoes occurred across Logan and Macon counties in central Illinois. One injury occurred in Logan County when a semi-truck was blown over by one of the tornadoes. In addition to the tornadoes, scattered wind damage also occurred.
